Tortuosity is widely used as a critical parameter to predict transport properties of porous
media, such as rocks and soils. But unlike other standard microstructural properties, the 

As an unconventional petroleum and gas resource, petroliferous shale pyrolysis can obtain
oil-retaining property-shale fuel similar to crude oil that can replace natural gas 

Convolutional neural networks (CNN) are utilized to encode the relation between initial
configurations of obstacles and three fundamental quantities in porous media: porosity () 

Gas shales contain a variety of clay-rich materials with multifarious pore networks. Clay-
hosted porosity is an essential component and considered to play a crucial role in 

Enhanced oil recovery (EOR) from shale oil formations is recognized as the next frontier in
the exploitation of unconventional resources. Current approaches for performing EOR 

Porosity and permeability are the key factors in assessing the hydrocarbon productivity of
unconventional (shale) reservoirs, which are complex in nature due to their heterogeneous 

Safe and efficient underground storage of hydrogen requires cap rocks with effective sealing
capabilities. This study investigates the interplay between various factors and their influence 

Injection of CO2 into shale reservoirs to enhance gas recovery and simultaneously
sequester greenhouse gases is a potential contributor towards the carbon-neutral target. It 

Porous membranes have been utilized intensively in a wide range of fields due to their
special characteristics and a rigorous characterization of their microstructures is crucial for 

This review examines new techniques and applications of organic petrography in source-
rock reservoir petroleum systems that have occurred along with development of the global
